### Description
I'm trying to use an SD Card with NXP IMXRT1176-EVKB board, i checked the
pins for the USDHC and the card is communicating, so no electrical or signal
integrity problems.

the problem is

i didnt edited the code DMA part, also i have this output when trying to
format

is there a setting i need to tweak in menuconfig?
